I examine a policy-making game among countries that must choose both a policy instrument (e.g., a tax or a quota) and its intensity (i.e., the tax rate or the quota level) to price pollution. When countries price pollution non-cooperatively, they not only set the intensity inefficiently, they...

Can trade agreements motivate environmental conservation? I first present a model whereby the government in the South expands its production capacity (e.g., deforest) before trading with the North. After deriving negative relationships between tariff reductions and conservation, I show how all...

This paper provides a flexible model of resource extraction, such as deforestation, and derives the optimal conservation contract. When property rights are "strong" and districts are in charge of extracting their own resources to get revenues, conservation in one district benefits the others...

In recent decades, democratic countries have signed hundreds of international environmental agreements (IEAs). Most of these agreements, however, are weak: they generally do not include effective enforcement or monitoring mechanisms. This is a puzzle in standard economic models. To study this...

Motivated by tropical deforestation, we analyze (i) a novel theory of resource extraction, (ii) the optimal conservation contract, (iii) when the donor prefers contracting with central rather than local governments, and (iv) how the donor's presence may induce institutional change. Deforestation...
